Research of a New Survey Method in Railway Engineering Based on Integration Technology of 3S Techniques

The terrain and geology of railways in mountain areas,like those in Yunnan,Guizhou,Sichuan and Tibet,are complicated,as well as its natural conditions.Because of some defects such as low efficiency,high risk,great difficulty and limited adaptability,the application of conventional survey method seems to be hard to meet the design requirements,especially in those sections with complicated natural conditions.In this case,for the purpose of solving problems during field survey of railway engineering in difficult and complicated mountainous areas,a new survey method is proposed after analyzing the advantages of the integration technology of 3 S techniques.Firstly,this paper expounds related digital softwares with integration technology of 3 S techniques,like Ovitalmap,and unmanned aerial vehicle,and the characteristics and advantages of novel mobile terminal.Secondly,a new process system related to field survey is summarized,meanwhile,the actual applications in railway projects are also introduced.Lastly,the comparative analysis of the newly proposed survey method and traditional ones is made and the main conclusions are as follows:the newly proposed method based on integration technology of 3 S techniques has features,like high precision,high efficiency,low risk and strong applicability,helping to solve problems efficiently during field survey of railway engineering in difficult and complicated mountainous areas.It can be popularized and applied in mountainous areas like those in Sichuan and Tibet.
